Emergent BioSolutions, the contractor that contaminated millions of coronavirus vaccine doses, hid evidence of problems from the F.D.A.
The disclosure, that Emergent hid evidence of quality control problems from federal inspectors in February 2021 — weeks before it alerted U.S. officials that millions of doses had been contaminated — came in a report released Tuesday by a Democratic-led House Committee.
No contaminated doses were ever released to the public.
